Banning cars from downtown areas always sparks fierce debate about killing local businesses, but the data from my city tells a different story. After Oslo pedestrianized its core, foot traffic rose by 14% and retail sales actually grew—people linger longer when they aren't dodging traffic. I've seen the same shift in my own neighborhood, where a car-free square now hosts weekend markets that didn't exist before. Critics claim it's bad for disabled access and deliveries, but those concerns can be managed with timed permits and exemptions. The real question is whether we're willing to trade a bit of driving convenience for streets that serve people, not just parked metal.
